Relativistic formulation of curl force, relativistic Kapitza equation and trapping
Partha Guha, Sudip Garai
In this present communication the relativistic formulation of the curl forces with saddle potentials has been performed. In particular, we formulated the relativistic version of th…

On the construction of almost general solutions for PDEs arising in nonlinear optics
A Ghose-Choudhury, Sudip Garai
In this communication we consider the widely used nonlinear Fokas-Lenells equation, the cubic focussing nonlinear Schrödinger equation in (2+1)-dimensions and the coupled Drinfel'd…

Integrable modulation, curl forces and parametric Kapitza equation with trapping and escaping
Partha Guha, Sudip Garai
In this present communication the integrable modulation problem has been applied to study parametric extension of the Kapitza rotating shaft problem, which is a protypical example…
